Technical Field

[0001] The utility model relates to the field of liquid level monitoring, in particular to a radar pressure dual liquid level monitor. Background Art

[0002] Radar level meter is a general radar level meter. It is a measuring instrument based on the time travel principle. Radar waves run at the speed of light. The running time can be converted into a level signal through electronic components. The probe emits a high-frequency pulse that propagates at the speed of light in space. When the pulse encounters the surface of the material, it is reflected back and received by the receiver in the instrument, and the distance signal is converted into a level signal.

[0003] In order to facilitate multi-environment liquid level detection, radar and pressure dual liquid level detection methods are used for corresponding detection. When the existing radar pressure dual liquid level meter is in use, the pressure probe will shake when it is lowered, affecting the accuracy of monitoring and causing inaccurate monitoring. For this reason, technical personnel in this field provide a radar pressure dual liquid level monitor to solve the problems raised in the above background technology. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figure 1-Figure 4The radar pressure dual liquid level monitor shown in the figure includes a monitor body 1 and a data rod 2 fixedly installed at the bottom of the monitor body 1, and also includes: a mounting box 5 fixedly installed at the bottom of the data rod 2, a radar cover 9 fixedly installed at one end of the mounting box 5, a pressure probe 6 is arranged at the other end of the mounting box 5, a mounting flange 7 is fixedly connected to the outer side of the data rod 2, and is used to install the monitor body 1 in the barrel wall of the liquid storage barrel; a wire-releasing mechanism 3 is used to adjust the height of the pressure probe 6, and the wire-releasing mechanism 3 is installed on the outer side of the data rod 2; a wire-clamping mechanism 4 is used to steadily release the pressure probe 6, and the wire-clamping mechanism 4 is installed inside the mounting box 5.

[0024] See also Figure 2-Figure 4 The pay-off mechanism 3 shown in the figure includes a mounting shell 301 fixedly mounted on the top of the mounting flange 7. An opening for mounting the data rod 2 is provided on the top of the mounting shell 301. A take-up drum 302 is installed on the outside of the data rod 2. A data cable 303 is installed between the bottom of the take-up drum 302 and the pressure probe 6. The take-up drum 302 adjusts the height of the pressure probe 6 through the data cable 303. The surfaces of the mounting flange 7 and the mounting box 5 are provided with through holes for limiting the sliding of the data cable 303. A gear ring 304 is fixedly connected to the outside of the take-up drum 302. The take-up reel 302 can drive the gear ring 304 to rotate synchronously. A gear 305 matching the gear ring 304 is installed in the installation box 5. A rotating rod 306 extending to the bottom of the installation flange 7 is fixedly connected to the inner side of the gear 305. A half roller 307 in contact with the outer side of the data cable 303 is fixedly connected to the end of the rotating rod 306 away from the gear 305. The outer side of the data cable 303 is pushed by the half roller 307 through repeated friction. An installation groove for the half roller 307 to limit the rotation is opened at one end of the installation box 5 close to the data cable 303.

[0025] The user can start the take-up drum 302 to release the pressure probe 6 on the data cable 303 downward, and when the take-up drum 302 rotates, the gear ring 304 drives the rotating rod 306 on the gear 305 to rotate, so that the rotating rod 306 drives the half roller 307 to rotate. When the arc surface of the half roller 307 contacts the outer side of the data cable 303, the data cable 303 is pushed to rotate, and when the plane of the half roller 307 rotates toward the data cable 303, the torque is used to return the data cable 303 to its original position, which can repeatedly rub and push the outer side of the data cable 303, so that the data cable 303 is released downward in a rotating and swinging manner, thereby preventing the data cable 303 from shaking significantly, thereby achieving the effect of smoothly adjusting the height.

[0026] See also Figure 4 and Figure 5The wire clamping mechanism 4 shown in the figure includes a stopper 401 installed inside the installation box 5, a cavity for limiting sliding of the stopper 401 is provided on the inner side of the installation groove, a spring 402 is fixedly connected between the stopper 401 and the inner wall of the cavity, a guide groove for installing the spring 402 is provided at one end of the stopper 401, and two guide plates 403 symmetrically distributed on both sides of the spring 402 are provided on the inner side of the guide groove for limiting sliding, so as to improve the stability of the movement of the stopper 401, and the guide plate 403 is fixedly installed on the inner wall of the cavity;

[0027] The stopper 401 can use the elasticity of the spring 402 to press against the outside of the data cable 303, so as to contact the outside of the half roller 307. When the data cable 303 is released downward, the arc surface of the half roller 307 can be attached to the outside of the data cable 303, thereby achieving a smooth release effect.

[0028] The working principle of smoothly delivering the pressure probe 6 is as follows: first, the user installs the monitor body 1 on the wall of the liquid storage barrel through the mounting flange 7, and starts the take-up drum 302, so that the take-up drum 302 delivers the pressure probe 6 on the data cable 303 downward, and the take-up drum 302 drives the rotating rod 306 on the gear 305 to rotate through the gear ring 304, so that the rotating rod 306 drives the half roller 307 to rotate, and when the arc surface of the half roller 307 contacts the outer side of the data cable 303, the data cable 303 is pushed to rotate, and When the plane of the half roller 307 rotates toward the data cable 303, the torque is used to return the data cable 303 to its original position, which can repeatedly rub and push the outer side of the data cable 303, so that the data cable 303 is released downward in a rotating and swinging manner, thereby preventing the data cable 303 from shaking significantly. In addition, the elasticity of the spring 402 is used to make the stop block 401 press against the outer side of the data cable 303, so that the arc surface of the half roller 307 is in contact with the outer side of the data cable 303, thereby achieving the effect of smoothly adjusting the height.

[0029] Embodiment 2

[0030] See also Figure 3-Figure 5 This embodiment further explains the first embodiment. The top of the mounting shell 301 in the figure is provided with a plurality of positioning grooves corresponding to the mounting holes of the mounting flange 7, which is convenient for installation through firmware. The end of the mounting box 5 close to the data cable 303 is provided with a positioning plate 8 for installing the rotating rod 306, so as to improve the stability of the rotation of the rotating rod 306.

[0031] In this embodiment, when installing the fastener, the user can press the nut against the positioning groove of the installation shell 301 to reduce the contact surface of the nut, making it easier to disassemble the nut during later maintenance, thereby facilitating installation.

[0032] Embodiment 3

[0033] See also Figure 4 and Figure 5 This implementation further illustrates other embodiments. The outer side of the half roller 307 shown in the figure is made of rubber material to increase the friction between the outer side of the half roller 307 and the data cable 303. The arc-shaped concave structure of the end of the stop block 401 away from the spring 402 facilitates the stop of the outer side of the data cable 303.

[0034] In this embodiment, the purpose is that when the half roller 307 rotates, the rubber material on the surface of the half roller 307 can be used to increase the friction between the half roller 307 and the data cable 303, so as to facilitate the rotation of the data cable 303.
